Dec 9, 2024

Checksum: a0552bc72ff7e18cb19e0a16ba72f0482697147fccb80abea4dec6273ca84e3c

These updates contain fixes for the following issues:

• Fix migration of VMs from Citrix Hypervisor 8.2 Cumulative Update 1 to XenServer 8 on Sapphire Rapids CPUs.
• In some circumstances the number of pIRQs for dom0 can be calculated incorrectly. As a result certain devices (for example, NICs) might not operate correctly.

Nov 27, 2024

Checksum: 1f743e21b4fe694ff98c7b2733e4e40283083b9c4428ab818139bce8b9256697

This update contain fixes for the following issues:

• The incorrect CSS expiry date was displayed in XenCenter alerts when the license server is temporarily inaccessible.
• When adding a host to a pool, XenCenter performs a case-sensitive Active Directory domain check, which might prevent hosts with the same domain name (differing only by case) from joining the pool.
• User certificates do not have SHA256 or SHA1 fingerprints after upgrading

This update includes the following improvements:

• The Windows Server 2025 guest template is no longer in preview and is now fully supported.

Nov 12, 2024

Checksum: e144b39fae499afb1b99dca54d881692f0cf3ac305c0b16bf22cbc0cc0cb47de

These updates include security fixes. For more information, see the XenServer and Citrix Hypervisor Security Update for CVE-2024-45818.

These updates include the following improvements:

• Update the Intel microcode to the IPU 2024.4 drop.

Oct 30, 2024

Checksum: f628a2a4a31d60754d9f08d9c98c23299d8b54ed6ac83e3ded7e108a15e33b60

These updates contain fixes for the following issues:

• On GFS2 and XFS SRs, a corruption issue might occur when taking an offline snapshot of a VDI that had been resized after creation, if and only if no data had been written to the VDI since the last snapshot. Online snapshots and other SRs are not affected.
• Older versions of the GFS2 storage repository might leave stray garbage collection marker files behind, preventing the use of the associated virtual disks. Stale marker files are now removed on startup.
• Possible crashes during some operations.

These updates include the following improvements:

• Improved reliability of the toolstack when under load.

Oct 21, 2024

Checksum: 5d651331af654bd851d603153450b8243fc4894224d2bd11c55121b4d7f8f9ed

These updates contain fixes for the following issues:

• A performance regression affecting writes to newly created virtual disk images (VDIs) on GFS2 and XFS storage repository (SR) types is fixed in this update. This issue affects VDIs created after the software updates released to Early Access on 9 October 2024 and to Normal on 16 October 2024. VDIs created before these updates, or after the update published on 21 October 2024, are unaffected.

  While this update resolves the performance regression, it does not automatically restore performance for impacted VMs due to the structure of the backing file created during the regression period. To restore performance:

  • For non-persistent or layered VMs (managed with Citrix Virtual Apps and Desktops MCS): Perform a base image update.
  • For persistent VMs (including master images): Take a snapshot to create a new backing file for future writes, which resolves the performance regression. Keep the snapshot until a future XenServer update is released to prevent the issue from reoccurring. Deleting it prematurely could result in the previous incorrect metadata structure being reapplied, reintroducing the performance issue.
  • For test VMs: Recreate them to resolve the issue.

Oct 16, 2024

Checksum: 388db9922915085c50ca4afb1b73b6f748905d752447988206ff45a69d424418

These updates include the following new features:

• Preview support for a new guest operating system: Windows Server 2025 (64-bit).

  Note:

  • When installing Windows Server 2025 VMs, having two disks attached might cause the VM to hang during boot. To avoid this issue, complete the installation with a single disk. Next, install VM Tools for Windows on the VM and reboot to finalize the installation. Once complete, you can safely attach the second disk.

  • If you boot a large number of Windows Server 2025 VMs on a single host, some might fail to start.

  For more information about the known issues for Windows guests, see Windows guests.

These updates contain fixes for the following issues:

• For XFS SRs, you cannot set the name or description of the SR.
• Bugfixes and improvements for SMAPIv3 SR types.
• The toolstack does not obtain the correct utilization numbers from a GFS2 SR.
• When an API client updates the blocked operations on a VM, XenCenter does not correctly update the allowed operations, resulting in certain permitted actions being incorrectly blocked.
• Fix a memory leak in xenopsd and implement memory tracking to prevent future leaks.
• The I/O priority management slice stops even though there are running VMs.

These updates contain upstream code changes for the following issues:

• CVE-2018-20679

These updates includes the following improvements:

Oct 02, 2024

Checksum: 0a4f1f9bf4df281ecb51eeaad4625c420c96fdf7bf81c8587dec39b73d3492e9

Important: These updates introduce a new restriction to Trial Edition. You can now use XenServer fora 90-day trial period after applying these updates. After the 90-day trial period expires, no VMs will start on your Trial Edition hosts and pools.

These updates include the following new features:

• VM anti-affinity: You can now assign your VMs to anti-affinity placement groups that are started on hosts in your pool according to the following anti-affinity placement rules:

  1. No single host is the only place a VM of a particular group is running.
  2. The count of VMs within the group for each host is as even as possible.

  When a VM in one of these groups is started or evacuated from a host, XenServer chooses to place the VM on a host that enables the VM group to follow these rules as closely as possible.

  For more information, see VM placement.

• Preview support for a new guest operating system: Ubuntu 24.04 (64-bit).

These updates contain fixes for the following issues:

• For some configurations of iSCSI SAN the expected number of iSCSI sessions were not created, reducing the effectiveness of multipath.
